Haier Power Pad takes energy from shower water and returns it to hot water system

The Haier PowerPad is a concept device shown at SinoCES which captures the energy contained within the water that runs off our bodies every morning in the shower, and returns said energy to the hot water tank. Haier claims the PowerPad is currently capturing and returning 15% of the energy coming out of the faucet and by the time it goes on sale six weeks from now, that figure will be 20-30%. Haier is one of the world’s most innovative companies and is hence foolish to bet against, but we’re struggling to understand the technologies being used and just how optimistic the claims are.
